IMPROVEMENTIN HEATING BUILDINGS.

TO LL WHOM IT MAY CONCERN: Y

Be it knownthat I, THOMAS BOYD,'oi` the city and county of Allegheny, in the State ofPennsylvania, have invented a new and useful Improvement for Heating Buildings; and I do hereby declare that the following is afull and exact description thereof', reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

The nature of myinventon consists in surrounding the ordinary fire-chamber and its smoke-hue with an air-chamber, which terminates in the fireplace of an upper room, said smokediue passing up into and .out of the fireplace of said upper chamber, into a sidc-iluc, thcl whole being constructed, arranged, and operating in the manner hereinafter described.

To enable others skilled in'rthe art to make and use my invention, I will proceed to describe its construction and operation. i

In the accompanying drawings, which form' partof my specication Figure 1 is a transverse section of an ordinary building, and represents a longitudinal scctioniof the chimney and its fireplaces, provided with my improvement.

Figure 2 is a longitudinal section of the chimney, showing a side view of it, and4 provided with-my improvement.

In the drawings, A represents the basement, B the first story, C the second story, and D the upper story` or attic of the building. :c represents the chimney-\valls.

In the first story,-B, is a fireplace, n, which consists of an ordinary grate, surrounded with a'hrick or metallic wall, marked 5, which is surrounded by an air-chamber, marked 3, and connected with a iiue, 2, which terminates in the fireplace m of the, second story. The fireplace n is provided with a sheet-iron smoke-flue, which passes up in the flue 2, into the iireplace m, and from it into a side-tine marked l. The ireplacem, in the second story, is provided with a fiue, marked 2, in which is placed a valve, o. It will readily bc observed that the llie 2.1nay'be provided with a. valve, and an openingr leading into each room above the second story C, so that the heat may be thrown into any room above the first story B by a simple manipulation of the valves.

The skillful mechanic will readily understand the construction and arrangement of my improvement from the foregoing description, and by reference to the accompanying drawings;` therefore I will at once proceed to` lcscribe its operation, which is as follows: f

Fire being made in the fireplace n, the smoke, dust, and other refuse`of combustion, will pass up through the {lue 4 into the ue marked 1, and up through it and out at the chimney-top. Cold air is admitted into the airchamber 3 through Vthe opening G. The air thus admitted becomes heated and rarefied, and passes up through the flue 2 into the replace m, from which it enters the room of the second story C. The temperature ofthe room of the second story may be regulated to any desired degree through the medium of the valve 0. It -will be observed that the air, after it loaves the chamber i3, is subjectedto the heat radiating from the iron flue 4, until it leaves the replaee m of the second story.

From the foregoing'description, and by reference to the accompanying drawings, it will readily be seen that the ilues 1, 2, and 2,.are straight, and that the smoke from the, fiue 4, and the dust from the Vash-chamber, pass into the side-tine 1, and that flue 4 can be removed and repaired readily, without the necessity of going on the root` of the house, or any disarrangernent of theY lines 1, 2, and 2. And it will also be observed that the construction of the chimney andits fines is greatly simplied, and more secure from the danger ofire than the dues of the ordinary chimney, for the draught is more direct and straight, and that lues are not so lihhle to become choked and clogged with soot, dust, and ,other refuse ofrcombustion.

The advantages of my improvement arc- First, the room or rooms abovethe first story can be heated when there is re .in the fireplace of the rst story, without cost.

-Second, the trouble of carrying fuel up stairs, and theashes and other refuse of combustion down stairs, isavoided. I

v Third, the dirt and dust consequent upon having a {irein the upper rooms, are avoided, hence thehodeewife is saved much trouble and labor. i

The ashchamber 6 of the fireplace u should-be connected with the flue marked 1, for the purpose ofcarrying oil' the dust caused by the stirring up the tire and the rattling down of ashes. This may be accomplished by making a `flue or opening to lead from the ash-chaniber 6 into the flue 1, as indicated by the dotted lines 7.

I Wish it clearly understood that I do not claim a stove placed in an ordinary fireplace, nor do I claim placing a pipe or pipes for heating air in the ilues of an ordinary fireplace; neither do I elairn broadly an airchamber around a fireplace, stove, or' other heating-device, Vand connecting therewith a pipe or pipes, for conducting heated air into upper ro'oms of buildings; but having thus described the nature, construction, operation, and advantages of my invention,

What I claim as of my invention, is

The arrangement of theilnes l, 2, 2, and 4, fireplaces m and n, air-chamber 3, and valve o, the whole being constructed, arranged, and operating as herein described, and for the purpose set forth.

THOS. BOYD.
